| TUBPA03 | Database Scheme for Unified Operation of SACLA / SPring-8 | 201 |
|
||
|
For reliable accelerator operation, it is essential to have a centralized data handling scheme, for such as unique equipment ID's, archive and online data from sensors, and operation points and calibration parameters those are to be restored upon a change in operation mode. Since 1996, when SPring-8 got in operation, a database system has been utilized for this role. However, as time passes the original design got shorthanded and new features equipped upon requests pushed up maintenance costs. For example, as SACLA started in 2010, we introduced a new data format for the shot by shot synchronized data. Also number of tables storing operation points and calibrations increased with various formats. Facing onto the upgrade project at the site*, it is the time to overhaul the whole scheme. In the plan, SACLA will be the high quality injector to a new storage ring while in operation as the XFEL user machine. To handle shot by shot multiple operation patterns, we plan to introduce a new scheme where multiple tables inherits a common parent table information. In this paper, we report the database design for the upgrade project and status of transition.

| TUPHA081 | Pilot Application of New Control System at SPring-8 RF Test Stand | 597 |
|
||
| After 20 years successful operation of SPring-8, the third generation synchrotron radiation facility, maintaining old analogue modules of LLRF system tend to be difficult. Meanwhile a digital technology like FPGA, fast ADC/DAC become popular. We decided to replace the old analog LLRF system with modern MTCA.4 based one. Prior to replacing the system, we planed to examine the performance of the new system at an RF test stand. An AMC digitizer and a RTM vector modulator were introduced. A feedback control function was reproduced in the FPGA of the digitizer. We also adopted EtherCAT for relatively slow control, such as a motor control for cavity tuner and monitoring of a vacuum pressure. In addition to developing the new hardware of MTCA.4, we were developing a new data acquisition system and a new MQTT based messaging system for an integrated control framework of SPring-8 and SACLA, the X-ray free electron laser facility. To prove feasibility of new control system, it was implemented at the RF test stand. As the result of high power RF operation, we achieved demanding stability of RF in the cavity. We also confirmed that new software framework was enough to control LLRF system. | ||

| FRAPL03 | Status of the Control System for the SACLA/SPring-8 Accelerator Complex | 1995 |
|
||
| At the SPring-8 site, the X-ray free electron laser facility, SACLA, and the third generation light source, SPring-8 storage ring, is operated. The SACLA generate brilliant coherent X-ray beams with wavelength of below 0.1nm and the SPring-8 provides brilliant X-ray to large number of experimental users. On the SPring-8 upgrade project we have a plan to use the linac of SACLA for a full-energy injector. For this purpose, two accelerators should be controlled seamlessly and the SACLA has to operate as to generate X-ray laser and injector for the SPring-8 simultaneously. We start the design of control system to meet those requirements. We redesign all of a control framework such as Database, Messaging System and Equipment Control include with NoSQL database, MQTT and EtherCAT. In this paper, we will report the design of control system for SACLA/SPring-8 together with status of the SPring-8 upgrade project. | ||
